How to Choose Between Die-Struck, Stamped, Etched and Cast

Start With Geometry, Not Finish

Most failed custom metal orders start with the wrong first question. Buyers ask for “the cheapest metal version” or “the nicest finish,” then discover the artwork cannot be reproduced cleanly in that process. The better starting point is geometry: raised lines, recessed areas, minimum text size, open spaces and relief depth determine whether the part should be die-struck, stamped, etched or cast.

That choice also affects repeatability. A design that looks acceptable in a sample can become unstable at scale if the process is too shallow, too soft or too dependent on hand polishing. For repeat programs, process selection should be locked before tooling, not after the first sample is already wrong.

• If the design is mostly flat with crisp outlines, start with stamped or die-struck.
• If you need recessed detail, small text or linework below 0.30 mm, consider etched.
• If you need sculpted volume, undercuts or strong 3D branding, cast is usually the better path.
• If the order must stay low-cost at scale, choose the simplest process that preserves the art.
• If the same item will be reordered for 6 to 24 months, favor the process with the most stable repeatability.

Know What Each Build Can Actually Hold

Die-struck and stamped are often used loosely in RFQs, but they are not identical in how they behave. Die-struck parts are pressed under higher force so the artwork carries stronger raised and recessed transitions. Stamped parts are typically flatter and faster to produce, which makes them efficient for badges, medallions, tags and minimalist logo pieces.

Etching is the right choice when the design carries more line detail than mass. Chemical etching can hold fine internal shapes better than a struck part, especially when the line width is around 0.20 to 0.30 mm and the buyer wants shallow relief rather than deep sculpting. Cast parts are different: they handle rounded forms, mascots and 3D volume better, but they can soften micro-detail if the artwork is too small or if mold cleanup is not controlled.

A practical design rule is to match the process to the feature you cannot afford to lose. If the logo depends on sharp outer edges and a heavy metal feel, go toward die-struck. If the logo depends on hairline internal detail, go toward etched. If the brand depends on volume and curvature, go toward cast.

Process	Best fit	Typical strengths	Common trade-off
Die-struck	Flat to medium-relief logos, coins, badges	Crisp edges, strong metal feel, good repeatability	Not ideal for deep undercuts or ultra-fine features
Stamped	Simple emblems, budget badges, thin-profile items	Lower cost, faster cycle time, clean silhouette	Limited depth and less sculptural detail
Etched	Fine lines, text-heavy art, shallow graphics	Good detail retention, lighter tooling burden	Shallower feel; may need fill or plating care
Cast	3D shapes, mascot forms, high-relief pieces	Best for form complexity and volume	Higher tooling cost; cleanup can blur micro-detail

Use a Spec Filter Before You Request Quotes

Before asking for pricing, convert the artwork into measurable specs. A strong factory can quote faster and more accurately when you provide the minimum line width, minimum gap, expected relief depth, overall thickness, plating finish and target quantity. Without that, suppliers often quote their preferred process instead of the process the artwork actually needs.

A practical filter is to look at the smallest readable detail. If text is under 1.2 mm high, raised elements are thinner than 0.30 mm or negative spaces are narrower than 0.25 mm, die-struck or cast may need design changes to survive production. For etched items, many factories prefer line widths of 0.20 to 0.25 mm and a minimum island or gap of 0.25 to 0.30 mm for stable repeatability. For cast items, very small internal corners should usually be relaxed to avoid fill loss during polishing.

You will get better quotes if you send the drawing in a format that answers process questions up front. That means stating the usable face size, the target thickness band, whether a rear logo or serial number is needed and whether the product must sit flush on fabric, packaging or a display base.

• Measure the thinnest line and narrowest gap in the artwork.
• State whether the piece must look premium from 30 cm or from 1 m.
• Specify whether sharp edges are acceptable or the item must feel soft in hand.
• Confirm whether the design will be reordered for 6 to 24 months.
• Ask the factory to flag any feature below its reliable process limit before sampling.
• Define the desired thickness band and the acceptable weight range, not just the appearance.

Compare Cost, MOQ and Lead Time

Price differences are driven by tooling, setup, reject risk and finishing labor more than by metal alone. Stamped parts usually sit at the lower end because they are efficient for simple shapes, while etched items remain competitive when the artwork is detailed but shallow. Cast pieces typically cost more because mold work is heavier and post-processing takes longer, especially if the product needs polishing in multiple directions.

For planning purposes, simple stamped or die-struck badges may land around USD 0.35 to 1.10 FOB at 1,000 to 3,000 pcs depending on size, plating and attachment. Etched items often sit around USD 0.55 to 1.60 FOB for similar quantities, while cast items frequently run USD 0.75 to 2.40 FOB or more when relief is deep or finishing is complex. Small MOQ runs of 100 to 300 pcs can push unit cost up sharply because setup time is spread across fewer pieces.

Typical factory planning tiers are straightforward: MOQ 100 to 300 pcs for cast samples or small runs, 300 to 500 pcs for etched or die-struck standard programs, and 500 to 1,000 pcs for the lowest pricing on repeat orders. Lead time commonly runs 7 to 10 days for sampling and 12 to 20 days for production after approval, with complex cast pieces reaching 15 to 25 days if tooling or polishing is heavy.

Decision factor	Die-struck / stamped	Etched	Cast
Artwork detail	Moderate	High on linework	High on 3D form
Tooling risk	Lower to moderate	Moderate	Higher
Typical MOQ tier	300 to 500 pcs	300 to 500 pcs	200 to 300 pcs
Sample lead time	7 to 10 days	7 to 10 days	8 to 12 days
Production lead time	12 to 20 days	12 to 22 days	15 to 25 days
Best use	Classic logos, medals, badges	Fine-detail graphics	Mascots, sculpted brands

Pick the Finish After the Build Is Decided

Finish choice should come after the process choice, not before it. A glossy gold or nickel plating can make a simple design feel premium, but it will also expose waviness, seams and tooling marks if the underlying metal work is not clean. Antique plating is more forgiving on texture and relief, which is why it is often used on die-struck and cast pieces that need depth and contrast.

Buyers should ask about plating thickness, not just color. Decorative flash plating is often around 0.05 to 0.10 microns for appearance only, while more durable decorative finishes are commonly 0.25 to 0.50 microns; heavier wear-resistant stacks can be higher depending on the substrate and process. If the item will be handled frequently, ask whether the surface uses clear lacquer, epoxy, e-coat or anti-tarnish protection, because finish failure is usually a system issue, not a color issue.

This is also where over-design becomes expensive. Mirror polish looks premium in a sample but exaggerates scratches and tooling marks in mass production. Matte, sandblasted, antique, brushed or dual-finish surfaces are usually more stable when the buyer wants repeatability across large orders or mixed production batches.

If the artwork includes recessed areas, ask whether the finish needs to be applied before or after any color fill. On deeper relief pieces, plating coverage inside recesses can vary by geometry, so a factory should confirm whether the color will sit on top, inside or between raised features.

When Detail, Weight and Feel Matter More Than Price

Some programs are judged by hand feel, not only by unit cost. Awards, executive gifts, collector pieces and premium membership items often benefit from cast construction because the added mass and curved relief create a stronger perception of value. But when the item must sit flat on fabric, remain light in transit or avoid snagging, a stamped or die-struck structure is usually safer.

Weight targets should be set early. A thin lapel badge may need to stay around 8 to 15 g to avoid pulling fabric, while a coin or desk piece can run 20 to 40 g if the use case supports it. Thickness is just as important: many light metal badges sit in the 1.2 to 1.5 mm range, while premium pieces often move into 2.0 to 3.0 mm, and some cast items go thicker if the design can support the added mass.

There is no universal best build here. If the item must look luxurious from arm’s length, cast may justify the higher tooling. If it must be distributed in the thousands at a trade show, die-struck or stamped often delivers better total value because it controls scrap, lead time and packing weight.

A useful way to decide is to compare failure modes. If the biggest risk is weak linework, etched is usually safer. If the biggest risk is a flat, cheap-looking impression, die-struck or cast may be worth the extra cost. If the biggest risk is budget pressure, stamped keeps the structure simple and the quoting clean.

Use a Quality Gate Before Mass Production

Your sample is not only for appearance; it is for process validation. The key question is whether the factory can repeat the shape, edge quality, plating coverage and attachment alignment across the full order without drifting outside tolerance. For metal promotional products, a practical buyer tolerance on major dimensions is often ±0.30 to ±0.50 mm depending on size, while hole positions and attachment points may need tighter control if the item must pair with packaging or hardware.

Ask for a pre-production sample and check the sharpness of edges, the cleanliness of recesses, the consistency of fill or polish and any distortion at thin points. If the design includes text, verify legibility at normal viewing distance rather than under a magnifier. For production control, many buyers use AQL 2.5 for major defects and AQL 4.0 for minor cosmetic issues; for premium gifting, some programs tighten cosmetic acceptance to AQL 1.5 on visible surfaces.

If the sample shows visible compromise, do not assume mass production will improve it. A weak corner, muddy recess or over-polished face usually becomes more obvious at scale, not less. The right process reduces the number of problems the factory has to fix by hand.

For higher-risk launches, define the inspection method in the PO. Common checks include visual inspection at 30 cm, caliper checks on overall size and thickness and adhesion testing on plating or color fill. If the product has moving parts, also confirm cycle count or pull-force requirements before approving production.

• Check the first sample under the same lighting the end customer will use.
• Measure major dimensions and critical hole locations, not only overall appearance.
• Confirm plating coverage in recesses, corners and around attachment points.
• Reject any sample with blurred text, filled corners or visible seam mismatch.
• Approve only after the sample matches the intended use, not just the artwork.

What to Do Next

Take the artwork and reduce it to four decisions: smallest feature, desired depth, target feel and acceptable unit cost. Then ask your supplier to recommend the process that best fits those constraints, not the process they prefer to sell. If the answer is unclear, request two quotes on the same art: one in stamped or die-struck form, one in etched or cast form, so you can compare real trade-offs rather than guess.

For a clean RFQ, send the drawing with thickness, finish, plating color, quantity tier, tolerance notes and packaging requirement. Include target MOQ, expected reorder window and any maximum unit weight if shipping cost matters. If you are still unsure, start with a sample run of 100 to 300 pcs and use that to validate both appearance and repeatability before moving to full production. That approach costs more upfront, but it is usually cheaper than reworking 5,000 pieces built in the wrong process.

A practical buyer brief looks like this: 1.8 mm overall thickness, antique nickel finish, 0.25 mm minimum line width, ±0.40 mm dimensional tolerance, AQL 2.5 major and 4.0 minor defects, 300 pcs initial order, 90-day reorder window and FOB target under USD 1.20. That level of specificity usually gets better factory answers than a generic request for “premium metal badges.”
